In part 1 of this Blog article I investigated the drag characteristics of the Tesla Cybertruck and explored how symmetry boundary conditions can be used to speed up a flow analysis project in SOLIDWORKS Flow Simulation. In part 2, I am going to demonstrate some of the nuances for correctly setting up a “Virtual Wind Tunnel” in SOLIDWORKS Flow Simulation. Before the widespread adoption of Computational Fluid Dynamics (CFD), engineers who sought to explore the aerodynamics of different vehicle shapes […]

SOLIDWORKS Flow Simulation: A Tesla Cybertruck Case Study

When Tesla launched their Cybertruck pickup model in November, I was intrigued by its unique shape. Given the very angular, wedge-like styling, the first thought that came to mind was that I could have designed the exterior shape in SOLIDWORKS in 5 minutes with a few extrudes, cuts and draft features. I have no doubt that I could have saved Tesla millions of dollars spent on their exterior stylists and designers! I also pondered whether this shape performed well aerodynamically […]

As time progresses and fuel prices increase, you might have noticed some changes to the tractor trailers you see on the highway. Fairings on tractors have been common for quite a while; however, side skirts and extended “tails” on the trailers are relatively new additions. To satisfy my curiosity on the effectiveness of these devices, I’ve performed a virtual experiment using Flow Simulation. Watch the quick video below to see the results of the test. For more training and tutorials […]
